Reported here is a new open-framework metal chalcogenide containing extra-large 36-ring channels. This compound has a 3-connected etc topology by regarding supertetrahedral T2 clusters as the structural nodes. It has a very low framework density (3.4 tetrahedra per 1000 Å3) with each framework cation participating in three 3-rings. The organic cations within its intersecting channels can be partially exchanged out by Cs+ ions with the preservation of its framework structure.
